Highly water-soluble as HCl salt

Best-Effort Research Profile

Metformin is an FDA-approved biguanide used with diet and exercise to improve glycemic control in type 2 diabetes. It lowers hepatic glucose production, reduces intestinal glucose absorption, and improves insulin sensitivity. Aging and longevity uses, including the proposed TAME program, remain investigational and do not create an approved anti-aging indication.

Source review pending. This descriptive profile is shown from the available source material as a best-effort educational reference. It has not passed the full verification bar and is not a dosing instruction, medical claim, or treatment recommendation.

Data source: Primary literature, regulator records, trial registries, and identity-specific evidence search

Reflects preclinical/research literature context only. Not a medical claim, dosing instruction, or treatment recommendation.

Route-Specific Research Protocols

Amounts and schedules are separated by administration route. Evidence badges distinguish labels, human studies, preclinical work, community reports, and evidence gaps.

Label / guideline Human study Community only Preclinical only Not established

Oral Preclinical only

Start 500 mg once or twice daily with meals and titrate to the selected product's labeled maximum

Frequency / timing: Daily in divided doses
Duration / setting: Ongoing with renal monitoring
Technique: Oral
Evidence: Preclinical / laboratory study

Context: current U.S. metformin labeling

Formulation: Oral-mucosal formulations are not dose-equivalent to injectable or topical formulations.

Route safety: Non-human or laboratory exposure. It cannot be converted into a human dose.

Do not convert an amount between routes. Bioavailability, formulation, sterility, monitoring, and clinical context differ by route. Research-use context only; independently verify every cited source.

Research Interactions

Flagged Avoid / Caution Combinations (Research)

eGFR below 30 mL/min/1.73 m2
Acute or chronic metabolic acidosis
Iodinated contrast without label-directed interruption assessment
Excessive alcohol use

Reflects patterns reported in research/community literature only. Not a safety guarantee, medical advice, or interaction warning for human use.

Research Notes

Prescription dosing is formulation- and renal-function-specific. The TAME aging trial is investigational and does not create an approved anti-aging indication.

Supplementary research context only. Not medical advice or a treatment recommendation.
